ATTACHMENT FOR SCREEN BARREL-COVERS.

SPECIFICATION forming part of Letters Patent No. 360,892, dated April 12, 1887.

Application filed January 17, 1887. Serial No. 231,616. (No model.)

each consisting of a flat iron plate bent or curved to correspond with the inside surface of a screen barrel-cover, and firmly attached thereto near the lower edge thereof, one directly opposite to the other. One of said plates has two sharp points-one near each extremity-pointing inward, and the other plate has a crank -screw with a sharp point screwed through the center of-said plate and pointing inward. By means of said crank-screw said points are easily and conveniently screwed or forced into the sides of said barrel, so that the screen cover is firmly held over the top of the barrel.

The object of my inventionis to so provide a fastening for the screen coverings of barrels containing fruit or other valuable produce, that the screens cannot be easily removed and such fruit or produce pilfered while on public exhibition in stores and sidewalks in cities or elsewhere.

My invention is fully illustrated in the accompanying drawings,in which Figure l is a screen barrel-cover placed over the top of a barrel, the lower edges of the cover cover, so that the sharp point of the crankscrew will comeiu contact with and penetrate the top of the barrel. Fig. 2 shows one of said attachments, with the crank-screw having a sharp point fastened to the lower edge of the screen cover, so that the sharp point of said screw may come in contact with and penetrate the top of the barrel. Fig. 3 is the other of said attachments, with the two sharp points 6 and e fastened in like manner to the lower edge of the screen cover so that the sharp points may penetrate the top of the barrel. Figs. 4. and 5 show the sharp points 0 and ein contact with the top of the barrel F and F.

The point e isscrewed through the iron plate by means ofthe crank-screw and made to penetrate the top of the barrel, whilethe outward pressure at this point is suff cient to draw the opposite pin, 6, into the top of the barrel. By simply turning the crank-screw, the cover is quickly and easily fastened to the top of the barrel.

Myinvention is very convenient,and ofgreat value to produce-dealers.

What Iclaim as my invention, and desire to secureby Letters Patent, is-

The two plates, one with the crank-screw and sharp point and the other with two sharp points, attached to the lower edge of a screen barrel-cover, so that the sharp points maybe made to penetrate the top of the barrel by means of the crank-screw, in the manner and for the purposes above set forth.
